Lightweight, compact, self-contained Spectrometer that measures the output of LED light sources and gives readings in Lux, Color Rendition Index (CRI), color temperature, and peak wavelength. The meter will read and measure visible light, but it is designed for LED lights and may not be as accurate when use to measure non-LED sources.
